* FILLING-.REPLENISHING LOOM.

SPECIFICATION forming part of Letters Patent No. l?24,120, dated March 31, 1903.

Application filed January 5, 1903. Serial No. 137,924. (No model.)

To all whom, it may concern:

Beitknown thatl, JONAS NORTHROP, asubject of' the King of Great Britain, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Filling-Replenishing Looms, of whichV the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. l

This invention relates more particularly to looms wherein 'the running-shuttle is provided automatically with filling, as in United States Patent No. 529,940.

When a fresh supply of filling is inserted in the shuttle and the latter is shot across the lay, the filling end extends from the hopper or filling-feeder to the cloth, and to cut this filling end and prevent it from breaking and weaving into the cloth a thread-cutter is provided, commonlyT mounted on the temple. In practice it has been found that very frequently this filling end will be struck by the inner end of the front box-Wall on the beatup and will draw over the Wall, and When the lay swings back the box-wall will again hit the fillin g end and slide beneath it. This sawing action is sometimes repeated so often that the filling end is broken before the threadcutter has severed it, as the cutter is not certain to sever the thread on the first beat-up after replenishment. breaking of the thread there is a great tendency to weave the end into the cloth, making an imperfection. The front box wall or plate has been shortened or cut down to avoid rubbing the filling end; but this is objectionable, as insufcient support is left for the shuttle.

My present invention has for its object the production of simple means for preventing the filling end from drawing or sawing overl the box-wall, as heretofore referred to, and it also serves to move the filling end into position to be parted by the thread-cutter.

The novel features of my invention Will be described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a front elevation of the replen- Of course with such a ishing shuttle-'box of an automatic loom with one embodiment of my invention applied thereto. Fig. 2 is a top or plan view thereof, showing the temple thread-cutter, the position of the front box-wall of the shuttle-box when the lay is forward being shown in dotted lines; and Fig.`8 is a detail inner end view of the boxfwall, showing the thread-engaging device thereon.

'lhelay A3, the replenishing shuttle-box BX, and the temple T, provided with a thread-cutter om, are and may be substantially as shown and described in United States .Patent No. 641,763, dated January 23, 1900, the fillingend holder b (see Adotted lines, Fig. 1) being the only part of the filling-feeder shown, said feeder constituting a part of the automatic fillingreplenishing mechanism, as will be manifest to those skilled in the art.

' lu the present embodiment of my invention Vthe front box Wall or plate B' of the replenishing shuttle-box has the inner end of its overhanging top or .flange b2 shaped to present a forwardly-extended projection b3, the top of said proj eetion'being slightly above the top of the box-Wall. (See Fig. 1.) The under face b4 of the projection is downwardly and rearwardly beveled, as best shown in Fig. 3, and terminates at the outer surface of the` box-Wall, thetop or flange b2 being preferably provided with a rounded notch b5 adjacent the outer side of the projection. notch the fiange is chamfered or rounded, as at b, for a purpose to be described. The filling end is shown at t,l it being supposed that after transfer of filling the shuttle S has been thrown across the lay from the box B and back again to said box, the filling end extending from the holding-plate b', Fig. 1, to the cloth. j

, In Figs. 1 and 2 the position of the filling end relative to the front box-Wall'B is shown in full lines when the lay is back. As the lay beats up the projection b3 passes over and above the filling end, and the beveled face b4 of said projection,'acting with the charnfered portion 66 of the top b2 of the box-wall, tends to push the filling end down beneath the part b" of the top. This is shown in-Fig. 2 in dotted Beyond this lines, the lay then being fully forward, and it will be seen that the lilling end is drawn into the range of' the temple thread-cutter to be severed thereby.

It is impossible for the filling end to draw across or saw over the top ot' the box-wall, because the beveled face b4 of the projection b3 acts to push it downward, and should the cutter fail to sever the filling end on the first forward beat of the lay the projection will again engage such filling end on the next beat and again present it to the cutter.

Manfestly the thread-engaging device will actlupon the filling end, as described, upon the first beat-up after transfer of filling, the shuttle then being iu the opposite shuttle-box.

Should the inclination of the lling end be greater than shown in Fig. l, it might pass into the notch b5 and under the projection b3 and still he prevented from drawing over the top of the box-wall.

Having fully described my invention, what I claim as new, and desire to secu re by Letters Patent, is-

l. In aloom provided with automatic filling-replenishing mechanism, a. shuttle-box, and a device on the front wall thereof having its front edge arranged to engage the fresh filling end on the beatup after replenishment and prevent it from rising and sawing over the box-wall as the shuttle-box moves back and forth.

2. In a loom provided with automatic filling-replenishing mechanism, a thread-cutter located adjacent the edge ofthe cloth, a shuttle-boX, and a device on the front wall thereof, to engage the fresh filling end on the beatup after replenishment and carry it into range of the cutter and also acting to prevent the filling end from rising or sawing over the boX wall as the shuttle-box moves back and forth.

3. In a loom provided with automatic lilling-replenishiug mechanism, including a filling-feeder, a temple thread-cutter, a shuttlebox, and a threadengaging device thereon to engage the fresh filling end between the fillingfeeder and thread-cutter on the beat-np and thereby direct said lling end to the cutter and also prevent it from rising over the shuttle-box.

4. A lay, a shuttle-box thereon, and a forwardlyextended projection thereon having a downwardly and rearwardly beveled under face to engage the filling end on the beat-up of the lay and prevent it from rising and drawing over the top of the shuttle-box.

5. A lay, a shuttle-box thereon, and a forwardly-extended projection on the front wall of the shuttle-box, near its inner end, to engage and pass over the filling end on the beatup of the lay and prevent it from rising and drawing over the top of the box-wall.

6. A lay, a shuttle-box thereon, the front Wall of which has an overhanging top, and a forwardly-extended projection thereon near the inner end of the wall, the said projection having'adownwardlyaud rearwardly beveled under face and the over-hanging top being chamfered beyond said projection, the beveled face of said projection engaging and depressing the filling end on the'beat-up of the lay, and causing such filling end to draw over the chamfered part of the overhanging top of the wall, to prevent the filling end from rising and sawing back and forth over the wall as the lay swings back and forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. t
